STM32 Nucleo-32 boards
Introduction
The STM32 Nucleo-32 boards (NUCLEO-F031K6, NUCLEO-F042K6, NUCLEO-F303K8,
NUCLEO-L011K4, NUCLEO-L031K6, NUCLEO-L412KB, NUCLEO-L432KC) provide an
affordable and flexible way for users to try out new concepts and build prototypes with
STM32 microcontrollers, choosing from the various combinations of performance, power
™
consumption and features. The Arduino
Nano connectivity support makes it easy to
expand the functionality of the Nucleo-32 open development platform with a wide choice of
specialized shields. The STM32 Nucleo-32 boards do not require any separate probe as
they integrate the ST-LINK/V2-1 debugger/programmer and come with the STM32
comprehensive software HAL library, together with various packaged software examples, as
®
™
well as direct access to the Arm
Mbed
online resources at http://mbed.org.

    EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability. In case the power supply is +3V3, the ST-LINK is not powered and cannot be used. 6.4.1 Power supply input from USB connector The STM32 Nucleo-32 board and shield board can be powered from the ST-LINK USB connector CN1.

  • Page 17: External Power Supply Inputs

    SB9 must be off. VIN or +5 V power supply When powered from VIN or +5 V, it is still possible to use ST-LINK for communication for programming or debugging only, but it is mandatory to power the board first, using VIN or +5 V, then to connect the USB cable to the PC.

  • Page 18: 3V3 Power Supply

    Using the +3V3 (CN4 pin 14) directly as power input, can be interesting, for instance, in case the 3.3 V is provided by a shield board. In this case the ST-LINK is not powered, thus programming and debugging features are not available. When the board is powered by +3V3 (CN4 pin 14), the solder bridge SB14 and SB9 (NRST) must be off.

    1. In applications where VCP is used for communication at a speed higher than 9600 bauds, it may be needed to use this solder bridge configuration, to use 8 MHz clock (MCO from ST-LINK) and get a more precise frequency.

    USART virtual communication Thanks to SB2 and SB3, the USART interface of STM32 available on PA2 (TX) and PA15 (RX), can be connected to ST-LINK/V2-1. When USART is not used it is possible to use PA2 as Arduino Nano A7. Refer to Table Table 7.
